What are two numbers that multiply to -15 and add to 19?

Answer 1

I'm sorry but there is no answer for that.

here is why:

if we formed this in an equation to find the answer - x^2+19x-15

then we try to factor

AC= (-15)

-15/1 = (15/1), (5/1), (3/1), (1), (-1), (-3/1), (-15/1)

15-1=-15*

15-1=14

-15+1=-14

3-5=-15*

3-5=-2

-3+5=2

none of these factors add up to 19 and so there is no rational numbers that multiply to -15 and add to 19
